Once you are ready to root the OnePlus 3T, you can follow these step by step instructions that will take you from start to finish.
As I mentioned yesterday, the process to install TWRP and root the OnePlus 3T is different when compared to the OnePlus 3. For this reason, I have decided to write up some dedicated tutorials specifically for the OnePlus 3T. Some of the guides are the same, and I will be editing those to let you know they will work on the OnePlus 3T as well. So while you’re going through these tutorials, be sure to check and see if it works for your device.
I will be referencing previous tutorials in the guide below. Some of those will also be referencing previous tutorials I have written. You’ll need to make sure you follow all of the steps included in those referenced tutorials. For instance, in the bootloader unlock guide, I talk about needing to have ADB and Fastboot tools installed so that you can install TWRP. So please be sure to follow all of these instructions as I walk you through gaining root access to the OnePlus 3T.
OnePlus 3T Root
- Unlock the bootloader of the OnePlus 3T
- Download the SuperSU .ZIP file to the OnePlus 3T
- Install TWRP on the OnePlus 3T
- Boot the OnePlus 3T into Recovery Mode (or stay in recovery mode after TWRP is installed).
- Tap on the Install button
- Browse to and tap on the SuperSU .ZIP file
- Swipe the white arrows to the right to confirm
- Wait for the installation to be completed
- Then tap on the Reboot System button toward the bottom right
Before you can even begin the process to root the OnePlus 3T, you will need to unlock the bootloader. This step will actually wipe all of the data from your phone so backup as much of it as possible before you begin. If Google has backed up your app data, then you can use it to restore your app/game installs after you sign into your account again. You’ll then want to download the SuperSU ZIP file to the OnePlus 3T. This can either be done directly on the phone, or downloaded to your device.
With that done, you can follow the steps I outlined for how to install TWRP on the OnePlus 3T. This can either be done directly on the phone, or downloaded to your device. Once TWRP is installed, you can do one of two things. You can either instantly root the device by flashing the SuperSU ZIP file here, or you can install the Disabler ZIP file that I link to in the tutorial for installing TWRP.
You just need to be in the TWRP recovery mode so that you can tap the Install button, browse to the SuperSU ZIP file, and then flash it to your OnePlus 3T. The process only takes a minute or two (as shown in the video above). Once the installation is finished, you should see a Reboot System button that appears toward the bottom right of the screen. Tap on that and the OnePlus 3T will instantly reboot.
It will seem like the phone is booting up, but it will reboot again during this first boot cycle. Just be patient, put in your PIN, pattern or password (twice) during the process and you should see the OnePlus 3T boot back into Android during the second boot cycle (again, as shown in the video above). This will only happen immediately after you have gained root access to the phone. All future reboots will work like normal.
Once you are back into Android, you can open up the App Drawer and you’ll find the SuperSU application icon right there. I like to launch this application to make sure it installed properly (since you’ll get an error if you open the app and the OnePlus 3T isn’t rooted).
